Acknowledgments

I would like to thank the many individuals who helped make this book possible. My wife, Ann, has been very supportive and encouraging. The many long hours of research and writing can cut into the hours of family time.

Many thanks to the several thousand students of all ages, as well as adults, who sent questions to me. Many of these questions came via their teachers. A special thank-you to you teachers, especially Rock Shutter, for sharing the contents of your students’ querying minds.

Thanks to the many fellow teachers and friends who critiqued some of my answers to questions. The same thanks goes to my three brothers and five sisters. I have turned to several medical personnel for advice, namely Dr. Scott Nicol, Dr. Alan Conway, Dr. Rod Erickson, and Dr. Rick Erdman. I received excellent advice from engineering instructors at UW–Milwaukee.

A big thank-you to the four thousand students that were enrolled in my science classes at Tomah High School, Tomah, Wisconsin. It was an honor to have you in my physics class for one or two years. I have many fond memories from close to forty years of teaching.

Thanks to Amy Fass, whose many hours of research and fact-checking improved the accuracy of this book. Thanks also to Karen Giangreco and Ruth Murray for providing excellent sketches and illustrations.

Finally, I am grateful to Matthew Lore, president and publisher of The Experiment, and his team, especially my editor, Nicholas Cizek, who provided suggestions for improvements and encouraged changes where needed. Ask a Science Teacher would not have been possible without their guidance.
